One and Two Step Equations

One Step Adding or Subtraction

100

x + 6 = 18

x = 12

200

x - 12 = 87

x = 99

300

x + 8 = -4

x = -12

400

x - 11 = -7

x = 4

500

34 + x = 14

x = -20

One Step Multiplying or Dividing

100

9x = 27

x = 3

200

x/10 = 6

x = 60

300

16x = 64

x = 4

400

x/3 = 25

x = 75

500

x/4 = 23

x = 92

Two Step Multiplying

100

2x + 10 = 14

x = 2

200

3x + 15 = 24

x = 3

300

2x - 4 = 20

x = 12

400

-12b - 4 = -28

b = 2

500

30 = 2 - 4x

-7 = x

Two Step Dividing

100

k/2 - 9 = 3

k = 24

200

m/3 - 10 = 5

m = 45

300

5 + k/4 = 8

k = 12

400

4 + a/-2 = 6

a = -4

500

- 2 = y/-3 - 12

y = -30
